Abstract (en)
[origin: WO9321764A1] Biologically active material is encapsulated by first blending such material with hardenable liquid, e.g., hardenable by polymerization, followed by dispersing the resultant composition in a non-flowable but stirrable aqueous gel, and hardening the dispersed droplets containing the biologically active material to form a stable dispersion of microcapsules containing such material in the gel.
